Effects of Mechanized Transplanting and Fertilization Mode on the Population Growth and Development of Male Parent in Hybrid Rice Seed Production
摘要
Abstract
In order to study the effects of mechanized transplanting and fertilization mode on the population growth and development of male parent in hybrid rice seed production,three male parents,Huazhan,Shuhui 527 and R9311 were used as material,the male parents were transplanted by rice transplanter with two line spaces design,six line with equal-row space (20/25 cm × 30 cm) and wide-narrow space (20/25 cm × 40,20 cm),artificial transplanting with equal-row space (20/25 cm ×30 cm) as the control.The three fertilization modes were applied once,twice and 3 times.The flowering stage and panicle-spikelet structure of the male parent were investigated.The result showed that the effects of mechanized transplanting and fertilization mode were little on the duration from seeding to heading;the panicles and spikelets of the three male parents were significantly increased by mechanized transplanting.The tiller number was increased by machanized transplanting and of fertilized twice and three times.Wide-narrow space by machine planting and fertilized three times were suitable for Huazhan,which significantly increased the number of spikelets per unit area.While,the number of spikelets per unit area of Shuhui 527 and R9311 were significantly increased by machanized transplanting,and fertilized three times.关键词
